Abstract
Description
- The present disclosure claims the priority of a
Chinese patent application with an application number of 201910352473.0 and a name of "sorting system" filed on April 29, 2019 - The present disclosure relates to the technical field of logistics devices, and in particular to a sorting system.
- In the logistics industry, when sorting packages, cross-belt sorters are usually used. Currently, the most commonly used sorters are circular cross-belt sorters and vertical cross-belt sorters. The cross-belt sorter is a closed conveying and sorting system composed of a group of trolleys, generally in a ring shape. Each trolley moves along a rail, and the surface belt of the trolley can rotate in the horizontal and vertical direction with respect to the movement of the trolley, so as to put the package into the respective grid. However, the circular cross-belt sorter and the vertical cross-belt sorter as currently used have a long turning radius and a long trolley pitch (where a trolley pitch refers to the distance between the central axis of two adjacent trolleys), which is usually 600mm. In this case, a small package also needs to occupy a trolley, resulting in a waste of transportation resources. In addition, when packages are transported on a trolley, they may be skewed thus causing throwing troubles. If the trolley pitch is large, a trolley only carries one package, which renders it difficult to achieve automatic package correction, and the correction will be not accurate.
- One of the main purposes of the present disclosure is to overcome at least one of the above-mentioned related technical defects, and provide a sorting system that can reduce the trolley pitch, save transportation resources, and can also transport conveying one package with multiple trolleys. Besides, a control system is also used to realize the automatic correction of the packet placement position, save manpower, and make the sorting more accurate.

It is easy for those skilled in the art to understand that, various modifications, additions, substitutions, deletions or other changes can be made to the following specific embodiments, in order to apply the relevant design of the present disclosure to other application scenarios, and these changes are still falling within the scope of the principle of the sorting system proposed in the present disclosure. - As shown in
FIG. 1 andFIG. 19 , in an embodiment, the sorting system proposed in the present disclosure can be used to transport packages 4. As shown inFig. 1 , the sorting system proposed in the present disclosure includes a conveying mechanism 1 and acontrol system 2. The conveying mechanism 1 includes arack 11, tworollers chain 12 and a plurality oftrolleys 13. The tworollers rack 11 at intervals along the first horizontal direction F1. Thechain 12 is wound between the tworollers FIGS. 1 ,5 and 6 , the plurality oftrolleys 13 are respectively connected to thechain 12 and arranged in sequence along the first horizontal direction F1. Eachtrolley 13 includes atrolley body 131 and a sorting and conveyingmechanism 132 provided on thetrolley body 131. The bottom part of the trolley body 131is connected to thechain 12. The sorting and conveyingmechanism 132 is configured to carry and convey packages along a second horizontal direction F2 perpendicular to the first horizontal direction F1. Thecontrol system 2 includes acontroller 21 connected to the conveying mechanism 1. Thecontroller 21 is configured to control the conveying mechanism 1 to transport the package 4 along the first horizontal direction F1, and is configured to independently control the sorting and conveyingmechanism 132 of eachtrolley 13 to convey the package 4 along the second horizontal direction F2. - With the above design, in the sorting system proposed by the present disclosure, the
trolley 13 is transporting in the first horizontal direction F1, transporting above therack 11, and sorting the package 4 and returning it below therack 11. Thus, pitch of thetrolley 13 can be reduced. For the transportation of smaller packages 4, the transportation resources are saved, and at the same time, the utilization rate of the occupied space is improved. Thecontrol system 2 controls the conveying mechanism 1 of thetrolley 13 and can independently control the sorting and conveyingmechanism 132 of eachtrolley 13. This helps to realize the automated transportation by the sorting system, saves labor, and can automatically control eachtrolley 13 to convey packages in the second horizontal direction F2, thereby realizing the more accurate throwing and correction of the package. - The
rack 11 extends along the first horizontal direction F1 to provide support for the entire conveying mechanism. The conveying mechanism 1 is a symmetrical structure. The following content in the present disclosure is a description of the structure from one side, and the structure from the other side is symmetrical to it. - The first horizontal direction F1 is the transportation direction of the
trolley 13, and the second horizontal direction F2 is the throwing direction of the package. Therefore, the second horizontal direction F2 is perpendicular to the first horizontal direction F1. In addition, thecontroller 21 in the present disclosure is electrically connected to the conveying mechanism 1. It can be a wired connection, such as through a USB interface, or a wireless connection, such as through Bluetooth or near field communication (NFC), infrared, etc., as long as the signal transmission between thecontroller 21 and the conveying mechanism 1 can be achieved, which is not limited here. - Furthermore, as shown in
FIGS. 2 to 4 , in an embodiment, therack 11 includes a rail for guiding thetrolley 13 to slide. Thetrolley 13 also includeswheels 133, which are arranged on respective sides of thetrolley body 131 thereof. In an embodiment, twowheels 133 are provided on one side and onewheel 133 is provided on the other side. Alternatively, twowheels 133 are provided on each side, which is not limited here. The rail may only have anupper rail 111, which is arranged on the inner side of the upper part of therack 11 and extends along the first horizontal direction F1. Thewheels 133 of thetrolley 13 are in sliding engagement with theupper rail 111, and theupper rail 111 serves as a support and guide part. Since the bottom part of thetrolley 13 is fixedly connected to thechain 12, thetrolley 13 can move in the first horizontal direction F1 along with thechain 12. Therefore, the rail can also only have alower rail 112, which is arranged along the inner side of the lower part of therack 11, and extends along the first horizontal direction F1. Thewheels 133 are slidably fitted with thelower rail 112, and slide along the first horizontal direction F1. Apparently, the rail can also have the above-mentionedupper rail 111 and thelower rail 112 at the same time, so as to provide support and guidance for thewheels 133 of thetrolley 13. It should be noted that the wording "inside" of therack 11 refers to the side of therack 11 close to its center line along the first horizontal direction F1. In the present disclosure, thetrolley 13 is arranged inside therack 11. - Furthermore, as shown in
FIGS. 2 to 3 , in an embodiment, therack 11 further includes anupper cover 114, one side of which is arranged on therack 11, and the other side of which extends above theupper rail 111 to cover thewheels 133 on theupper rail 111, to prevent foreign objects from falling therein. Specifically, one side of theupper cover 114 may be arranged on the top end of therack 11 or on the inner side of therack 11, and the other side of theupper cover 114 may extend along the second horizontal direction F2 to cover thewheels 133. - Furthermore, as shown in
FIGS. 4 to 6 , in an embodiment, eachwheel 133 further includes awheel body 1331 and awheel shaft 1332. Thewheel shaft 1332 penetrates through thewheel body 1331, and a gap exists between the end of thewheel shaft 1332 close to therack 11 and the inner side of therack 11, which gap is set to be 1 to 5 mm. This gap has a small value, so that therack 11 limits the position of thetrolley 13. When thetrolley 13 throws a package, the end surface of the wheel shaft can contact the inner side of therack 11 to prevent thetrolley 13 from shaking significantly along the second horizontal direction F2. - Furthermore, as shown in
FIG. 3 , in an embodiment, the end surface of thewheel shaft 1332 at one end close to therack 11 is a curved surface, so as to reduce the wearing when thewheel shaft 1332 contacts the inner side of therack 11. - Furthermore, as shown in
FIGS. 2 to 3 , in an embodiment, therack 11 further includes a wear-resistant strip 115. The wear-resistant strip 115 is made of wear-resistant material. The wear-resistant strip 115 is arranged on the inner side of therack 11 along the first horizontal direction F1 and is located between theupper cover 114 and theupper rail 111, so as to prevent the abrasion caused by the lont-term contact between the inner side of therack 11 and thewheel shaft 1332. - Further, in an embodiment, the wear-resistant material of the wear-
resistant strip 115 is ultra-high molecular weight polyethylene. Of course, it can also be other wear-resistant materials, which is not limited here. - Further, as shown in
FIGS. 1 and7 , therack 11 in an embodiment further includes shock-absorbingfeet 113, which are arranged on respective sides of therack 11 to support therack 11. It can be seen from the figures that there are multiple shock-absorbingfeet 113, which are arranged on respective sides of therack 11 and arranged at intervals. This helps to reduce the vibration of each section of therack 11 and prevent the ground and the equipment platform from being penetrated by the vibration. - Further, as shown in
Figures 1 ,7 to 8 , in an embodiment, one of the tworollers roller 15, of the conveying mechanism 1 is anactive roller 151, and the other roller is apassive roller 161. The drivingroller 151 includes a drivingsprocket 1511, a drivingshaft 1512, abearing seat 1513, and a drivingmotor 1514. The drivingsprocket 1511 meshes with thechain 12. The bearingseat 1513 is arranged on therack 11. The drivingshaft 1512 passes through the center part of the drivingsprocket 1511, and has two ends passing through thebearing seat 1513. The drivingmotor 1514 is in a transmission connection with the drivingshaft 1512, and is configured to drive the drivingshaft 1512 to rotate and drive the drivingsprocket 1511 to rotate. That is, theactive roller 151 is used to provide power for the entire conveying mechanism 1 and to make thechain 12 rotate. - Specifically, as shown in
FIG. 8 , in an embodiment, a connecting plate is provided on one side of therack 11 corresponding to the drivingshaft 1512, and a plurality of elongated holes are opened on the connecting plate. The bearingseat 1513 is fixed onto the connecting plate by bolts, and the bolts pass through the elongated holes. In addition, the upper and lower ends of the connecting plate have flanges protruding in the second horizontal direction F2. A threaded hole is opened in the lower flange at a position facing the bearingseat 1513, and at least one height adjustment bolt is pressed against the bottom part of thebearing seat 1513 through the threaded hole. On the one hand, the height adjustment bolt provides support for thebearing seat 1513. On the other hand, according to actual needs, when installing the drivingshaft 1512 and thebearing seat 1513, the height of thebearing seat 1513 can be adjusted along the elongated hole and then tightened. The height adjustment bolt realizes the fine adjustment of the height of the drivingshaft 1512, so that a good running effect is achieved by the sprocket. - Further, as shown in
FIG. 6 , the conveying mechanism 1 further includes a connectingpiece 17 through which thechain 12 is connected to the bottom part of thetrolley 13. Specifically, the connectingpiece 17 may be a right-angle connecting plate, and thechain 12 is connected to the bottom part of thetrolley 13 by bolts. - It should be noted that the
chain 12 is connected to the bottom part of thetrolley 13 through the connectingpiece 17. The "bottom part" in the present disclosure refers to the part near thechain 12 when thetrolley 13 runs along the first horizontal direction F1 on theupper rail 111. When thetrolley 13 runs along the first horizontal direction F1 on thelower rail 112, the "bottom part" of thetrolley 13 is still the side close to thechain 12, not the side close to the bottom surface. - Further, as shown in
FIGS. 9 to 12 , in an embodiment, one of the tworollers active roller 151, and the other is apassive roller 161. Thepassive roller 161 includes atension sprocket 1611, atension shaft 1612 and atension assembly 1613. Thetension sprocket 1611 meshes with thechain 12. Thetension shaft 1612 passes through the center part of thetension sprocket 1611. Thetension assembly 1613 is connected to the end of thetension shaft 1612, and is configured to adjust the tension degree of thechain 12 by adjusting the displacement of thetension shaft 1612 in the first horizontal direction F1. - Further, as shown in
FIGS. 9 to 12 , in an embodiment, thetension assembly 1613 includes a slidingrail 16131, a tension spring 16134, atension rod 16136, and an elasticity adjustment component 16137. - The sliding
rail 16131 is fixedly arranged on therack 11 along the first horizontal direction F1, as shown inFIG. 12 . In one embodiment, the slidingrail 16131 is connected to therack 11 by bolts. The slidingrail 16131 is provided with a slidinggroove 16132 penetrating along the second horizontal direction F2, and the end of thetension shaft 1612 penetrates through the slidinggroove 16132 along the second horizontal direction F2. The slidingrail 16131 is further provided with anopening 16133 at one end away from theactive roller 151, and theopening 16133 is in a communication connection with the slidinggroove 16132. - Further, as shown in
Figures 10 and11 , thetension assembly 1613 further includes abaffle 16138 connected to the end surface of thetension shaft 1612. Thebaffle 16138 is provided on the side of the slidingrail 16131 away from thetension sprocket 1611, and the size of thebaffle 16138 in the vertical direction is larger than the width of the slidinggroove 16132. The purpose of setting thebaffle 16138 here is to prevent thetension shaft 1612 from sliding out from the side of the slidinggroove 16132, and thebaffle 16138 plays a guiding role. Specifically, as shown inFigures 10 and11 , the cross-sectional shape of thebaffle 16138 is C-shaped, and two guide grooves are provided on both the upper and lower sides of the slidinggroove 16132 of theslide rail 16131, which are used to mate with the two sides of thebaffle 16138. It should be noted that, in an embodiment, the vertical direction refers to a direction perpendicular to and away from the ground. - The tension spring 16134 is connected to one end of the sliding
rail 16131 with theopening 16133 along the first horizontal direction F1. The tension spring 16134 has a cavity 16135 extending along the first horizontal direction F1, and the cavity 16135 is in communication with theopening 16133. - The
tension rod 16136 passes through the cavity 16135 of the tension spring 16134 and the slidinggroove 16132 of the slidingrail 16131 in sequence along the first horizontal direction F1. The end of thetension rod 16136 located in the slidinggroove 16132 of the slidingrail 16131 is defined as the first end, and the other end of thetension rod 16136 located in the slidinggroove 16132 is defined as the second end. The first end of thetension rod 16136 is connected to the end of thetension shaft 1612. When thetension rod 16136 moves along the first horizontal direction F1, the end of thetension shaft 1612 can be driven to slide along the first horizontal direction F1 in the slidinggroove 16132. The second end of thetension rod 16136 extends out of the tension spring 16134. Reference is made toFIG. 12 . In an embodiment, the cross section of the slidinggroove 16132 is T-shaped. Specifically, it is a shape obtained after the T-shaped cross section is rotated 90° clockwise. The slidinggroove 16132 can be divided into a first through groove and a second through groove. The first through groove is a rectangle shape extending in the first horizontal direction F1, and the second through groove is a rectangle shape extending in the vertical direction (a direction perpendicular to the ground). The first through groove and the second through groove are in communication with each other. The width of the rectangle-shaped first through groove matches the size of thetension shaft 1612, so that thetension shaft 1612 can slide along the upper and lower sides of the rectangle-shaped first through groove to limit thetension shaft 1612 in position and prevent thetension shaft 1612 from swayingup and down in the vertical direction. The second through groove extends in the vertical direction. The purpose is to facilitate the assembly of thetension rod 16136 and the tension shaft in the second through groove, completing the connection, and then moving into the first through groove. - The surface of the
tension rod 16136 has threads. For example, thetension rod 16136 is a screw, and one end of the screw is fixedly connected to thetension shaft 1612. Thetension rod 16136 may also be a threaded rod. Of course, in one embodiment, thetension rod 16136 may be a rod without threads, as long as one end of the tension rod can be fixedly connected to the shaft 9, which is not limited here. - The elasticity adjustment component 16137 is arranged at one end of the tension spring 16134 away from the sliding rail 15231, connects the
tension rod 16136 and the tension spring 16134, and compresses or stretches the tension spring 16134. The elasticity adjustment component 16137 may be a nut. As shown inFIG. 12 , in an embodiment, the tension spring 16134 is initially in a compressed state to provide pre-tension force for thetension rod 16136. The elasticity adjustment component 16137 can adjust the compression length of the spring, thereby adjusting the magnitude of the pre-tension force. When thechain 12 becomes loose, the tension spring 16134 will elongate, driving thetension rod 16136 to move away from theactive roller 151, and then driving thetension shaft 1612 to slide along the sliding groove 15232 to tension thechain 12. In another embodiment, when thetension assembly 1613 is installed in a direction opposite to the first horizontal direction F1 inFIGS. 11 and 12 , it can be set to stretch the tension spring 16134 to provide pre-tension force in the same direction. Therefore, thetension assembly 1613 of the present disclosure can automatically perform tension compensation after thechain 12 is stretched due to long-term operation, so as to avoid undesirable phenomena caused by thechain 12 being slack, out of gear or jumping gear and the like. - Further, as shown in
FIGS. 11 and13 , in an embodiment, the conveying mechanism 1 further includes a first shock-adsorbingrail 18 and/or a second shock-adsorbingrail 19. The first shock-adsorbingrail 18 is arranged inside therack 11 and extends along the end of thelower rail 112. The upper surface of the first shock-adsorbingrail 18 is gradually reduced from the upper surface of thelower rail 112 to a wedge-shaped surface, so that the wheels of thetrolley 13 133 are transitioned to thelower rail 112 for sliding. The second shock-absorbingrail 19 is arranged inside therack 11 and extends along the end of theupper rail 111. The upper surface of the second shock-absorbingrail 19 is gradually reduced from the upper surface of theupper rail 111 to a wedge-shaped surface, so that the wheels of thetrolley 13 are transitioned to theupper rail 111 for sliding. As shown inFigure 13 , when thetrolley 13 rotates back from the drivingsprocket 1511 or thetension sprocket 1611, and the line connecting thewheels 133 of thetrolley 13 and the axle center of the drivingsprocket 1511 or thetension sprocket 1611 is perpendicular to the ground, thewheels 133 of thetrolley 13 are at the lowest position, and the distance below the lowest position of thewheels 133 in the horizontal section is c. The height of the connection part between the first shock-adsorbingrail 18 and the second shock-adsorbingrail 19 and theupper rail 111 or thelower rail 112 is a, and the height of the ends thereof is b, wherein a>b. Thewheels 133 of thetrolley 13 are transisioned to theupper rail 111 or thelower rail 112 through the first shock-adsorbingrail 18 and the second shock-adsorbingrail 19, so as to prevent thewheels 133 from directly colliding with theupper rail 111 or thelower rail 112, thereby reducing noise and protecting thetrolley 13. Reference is made toFig. 1 . When the transport direction of thetrolley 13 is from thepassive roller 161 to theactive roller 151, in one embodiment, the first anti- vibration rail is arranged on thelower rail 112 corresponding to theactive roller 151, and the second anti-vibration rail is arranged on theupper rail 111 corresponding to thepassive roller 161. Of course, the first anti-vibration rail and the second anti-vibration rail can also be arranged at thelower rail 112 and theupper rail 111 corresponding to theactive roller 151 and thelower rail 112 and theupper rail 111 corresponding to thepassive roller 161. When adjustment is made to the transport direction of thetrolley 13, the shock absorption effect can be achieved. In an embodiment, only the first shock-adsorbingrail 18 may be provided, or only the second shock-adsorbingrail 19 may be provided, which is not limited here according to actual needs. - Further, in an embodiment, materials of the first shock-adsorbing
rail 18 and the second shock-adsorbingrail 19 are both ultra-high molecular weight polyethylene with high wear resistance. - Further, as shown in
FIG. 14 , in an embodiment, the sorting system further includes apackage supply mechanism 3, and thepackage supply mechanism 3 includes apackage supply rack 31 and apackage supply belt 32. Thepackage supply belt 32 is arranged on thepackage supply rack 31 and is configured to transport the package 4 to thetrolley 13. - Furthermore, as shown in
FIG. 2 , the conveying mechanism 1 of the sorting system further includes a guide table 14, corresponding to each throwing grid and arranged on respective sides of therack 11, wherein the package has been led out of the conveying mechanism through the throwing opening. - Further, as shown in
FIGS. 15 to 19 , in an embodiment, thecontrol system 2 further includes adata acquisition module 22. Thedata acquisition module 22 includes acode scanner 221. Thecode scanner 221 is configured to collect the sorting information of the package 4. Thecontroller 21 is connected to thecode scanner 221. Based on the sorting information collected by thecode scanner 221, thecontroller 21 can determine the throwing grid of the package 4 to be delivered, and control the movement of the conveying mechanism 1 along the first horizontal direction F1 and the movement of the sorting and conveyingmechanism 132 of eachtrolley 13 along the second horizontal direction F2, causing the package 4 to be thrown to the designated throwing grid. Reference is made toFIG. 2 , where a guide table 14 is also provided for exporting the package 4 to the conveying mechanism. The throwing grid designated in the present disclosure refers to the grid corresponding to the guide table, which is used to transfer the package 4 from the trolley to the guide table 14. - Specifically, in an embodiment, the
code scanner 221 can be set on thepackage supply rack 31 or on therack 11 of the conveying mechanism, as long as the sorting information of the package 4 can be read before transportation. It is not limited here. Thecode scanner 221 reads the label on the package and sends the sorting information on the label to thecontroller 21. Thecontroller 21 obtains the destination grid of the package 4 from its internal database according to the sorting information, and then controls the conveying mechanism 1 to transport the package 4 to the destination grid. After that, the sorting and conveyingmechanism 132 on thetrolley 13 carrying the package is separately controlled to move along the second horizontal direction F2 to throw the package. - Reference is made to
FIG. 5 . In an embodiment, the sorting and conveyingmechanism 132 on thetrolley 13 includes two rollers and a conveyingbelt 1323 wound on the two rollers. One of the two rollers is a drivingroller 1321 and the other is atension roller 1322. The drivingroller 1321 and thetension roller 1322 are both arranged on thetrolley body 131 and they are arranged at intervals. Thecontroller 21 is electrically connected to the drivingroller 1321, and controls start, stop, and adjustment of the rotation speed and rotation direction of the drivingroller 1321, so as to control the forward or reverse movement of the conveyingbelt 1323 in the second horizontal direction F2, thereby adjusting the position of the package 4 and putting the package 4 in a proper orientation (as shown inFigure 19 ). Regarding how thecontroller 21 is electrically connected to the drivingroller 1321 and how to realize the control of the drivingroller 1321, those skilled in the art can implement according to related technologies. For example, an encoder can be provided on each drivingroller 1321, and a control signal can be received from thecontroller 21, or other means can be used, which will not be repeated here. Therefore, thecontroller 21 can control start, rotation speed and rotation direction of the drivingroller 1321 on thetrolley 13 according to the sorting information collected by thecode scanner 221, and make sure the package 4 is thrown to the correct grid. - Further, as shown in
FIGS. 15 to 19 , in an embodiment, thedata acquisition module 22 further includes aposition sensor 222, which is configured to detect the first position information of the package 4 at the initial position. Thecontroller 21 is connected to theposition sensor 222 and independently controls the sorting and conveyingmechanism 132 of eachtrolley 13 according to the first position information of the package 4 so as to adjust the position of the package 4. - Specifically, in an embodiment, the
position sensor 222 can be arranged on thepackage supply rack 31 or on therack 11 of the conveying mechanism, as long as the first position information of the package 4 can be read, and it is not limited here. The first position information may include the size of the package 4, the size offset from the center line of thetrolley 13 along the first horizontal direction F1 (that is, when the package is in a skewed state), and the like. Theposition sensor 222 sends such position parameter to thecontroller 21, and thecontroller 21 independently controls the movement of the sorting and conveyingmechanism 132 of thetrolley 13 carrying the package 4 in the second horizontal direction F2 according to the first position information. As shown inFig. 19 , thecontroller 21 controls the activation of the driving roller of therespective trolley 13 according to the first position information, and adjusts the rotation speed, rotation direction of the driving roller of eachtrolley 13 and also the displacement of the conveying belt along the second horizontal direction F2, so as to move the package 4 to the middle position of thetrolley 13. That is, the center line of the package 4 and the center line of thetrolley 13 coincide in the first horizontal direction F1. - Further, in an embodiment, the
data acquisition module 22 further includes a detection sensor (not shown in the figures), which is configured to detect the second position information of the package 4 at the adjustment position. It may be that after the initial position of the package 4 is adjusted, it is transported to the adjustment position, and the position is adjusted for a second time. Thecontroller 21 is electrically connected to the detection sensor, and independently controls the sorting and conveyingmechanism 132 of eachtrolley 13 according to the second position information of the package 4 to assist in adjusting the position of the package 4. The function of the detection sensor is to collect for a second time the position parameters of the package that has been adjusted, and send the position parameter information to thecontroller 21. If thecontroller 21 determines that the package 4 is still in a skewed state, it will further adjust the driving roller of therespective trolley 13, so as to adjust the package 4 to the middle position of thetrolley 13. If the package 4 is still in a skewed state after re-adjustment, it can be manually adjusted or dropped in advance or later. - The initial position refers to a position where the package 4 is placed on the sorting trolley and has not yet been transported, or placed on another mechanism capable of transporting the package to the sorting
trolley 13, such as thepackage supply rack 31. The adjustment position refers to a position where the package 4 is located after being transported for a certain period of time from the initial position. Such period of time is not a specific value, and it can be adjusted according to actual conditions. - For example, in an embodiment, the
position sensor 222 may be arranged on thepackage supply rack 31 of the sorter, and the package 4 is first placed on the package supply belt 32 (at the initial position). Theposition sensor 222 collects the position parameter (or the first position information) of the package 4 and sends it to thecontroller 21. Themultiple sorting trolleys 13 located on the sorter rack can be divided into an adjustment area and a transportation area along the first horizontal direction F1. The package 4 is transported to the adjustment area (or the adjustment position) via thepackage supply belt 32. Thecontroller 21 controls the electric roller of thecorresponding sorting trolley 13 to adjust the position of the package 4 in the adjustment area. After that, the detection sensor detects the adjusted position parameter (or the second position information) of the package. If the adjusted position parameter meets the requirements for putting the package in a proper orientation, thecontroller 21 controls the conveying mechanism 1 to transport the package 4 to the transportation area. If the adjusted position parameter does not meet the requirements for putting the package in a proper orientation, thecontroller 21 will re-control the electric roller to adjust the position of the package 4 according to the adjusted position parameter (or the second position information). In an embodiment, the detection sensor may be a detection camera, which is arranged directly above the adjustment area, takes a picture of the package, and sends the image information to thecontroller 21. Alternatively, the detection sensor may also be an encoder, which is arranged on each sortingtrolley 13 to detect the position parameter of the package on the sortingtrolley 13 and send the position parameter to thecontroller 21. Therefore, the sortingtrolley 13 in the present disclosure can realize the automatic position adjustment of the package, so that the throwing and dropping is more accurate, and at the same time, the amount of manual labor is saved. - Further, as shown in
FIG. 10 , in an embodiment, thedata acquisition module 22 further includes atension sensor 224. Thetension sensor 224 is arranged on therack 11, electrically connected to thecontroller 21, opposite to thetension assembly 1613 in the first horizontal direction F1, and configured to detect the distance between thetension sensor 224 and thetension assembly 1613. The distance is sent to thecontroller 21 in the form of an electric signal. At the same time, thetension sensor 224 can also detect the distance X moved by thetension sprocket 1611 due to the looseness of thechain 12. If it is detected that the difference in the distance X between the two sides of thetension sprocket 1611 is large, it means that thechains 12 are inconsistent in stretching on both sides, and thechain 12 of the device needs to be adjusted to prevent further damage to the device. - Further, continuing referring to
FIG. 10 , in an embodiment, thedata acquisition module 22 further includes asensing piece 225. Thesensing piece 225 is disposed at the second end of thetension rod 16136. Thetension sensor 224 is opposite to thesensing piece 225 in the first horizontal direction F1, and is configured to detect the distance between the tension sensor and thesensing piece 225. Thecontroller 21 determines the amount of deformation of the tension spring 16134 according to the distance. When the tension spring 16134 stretches too long and the elastic force decreases, it will issue a prompt and notify the staff to make adjustments accordingly. - Furthermore, as shown in
FIG. 3 , thedata acquisition module 22 further includes a first-trolley sensing piece 231 and a first-trolley detection sensor 232. The first-trolley sensing piece 231 and the first-trolley detection sensor 232 are installed on anytrolley 13, and the first-trolley sensing piece 232 is connected to thecontroller 21. When the conveying mechanism 1 starts to operate, the first-trolley sensing piece 232 will trigger the first-trolley sensor 231 at regular intervals. By providing the first-trolley detection sensor 232, the position of the first trolley at the trigger time can be known, and thecontroller 21 can calculate the accurate position of anyother trolley 13 at the trigger time. The calculation method is as follows, where it is supposed that the pitch of thechain 12 is P, and every N links of thechain 12 are connected to the bottom part of thetrolley 13 through the connectingpiece 17. Thus, the initial pitch of thetrolley 13 can be obtained as P0=N∗P, where N is a positive integer, and 1≤N≤20. In an embodiment, P=50.8 and N=6. In addition, thetension sensor 224 needs to sense the distance X moved by thetension sprocket 1611 and send it to thecontroller 21. Assuming that the number oftrolleys 13 is N1, the pitch P1 of twoadjacent trolleys 13 is 2X/N1+P0, and the distance from the first one to the last one among Nadjacent trolleys 13 is N∗P1. - Further, referring to
FIG. 7 , in an embodiment, a drivingencoder 233 is also provided on the drivingmotor 1514, and the drivingencoder 233 is connected to thecontroller 21 for detecting and controlling the rotation speed of the drivingsprocket 1511. - The specific structure and connection relationship between the
control system 2 and the conveying mechanism 1 in an embodiment will be described in detail below. Referring toFIG. 18 , where two sides of therack 11 are respectively provided with a slidingcontact wire 226 and anexternal antenna 228. The slidingcontact wire 226 is connected to a power source to provide power for the sorting system. Theexternal antenna 228 is connected to thecontroller 21 and used for transmitting the command signal of thecontroller 21. Reference is made toFIG. 15 , where at least one of thetrolleys 13 is provided with an electric pickup set 227 at the bottom part of thetrolley 13. The electric pickup set 227 is in contact with the slidingcontact wire 226, so as to obtain power from the slidingcontact wire 226 and supply it toother trolleys 13. A power line can be set between thetrolleys 13, and onetrolley 13 can supply power tomultiple trolleys 13. Reference is made toFIG. 16 , where asignal transceiver 229 is provided at the bottom part of at least one of thetrolleys 13. Thesignal transceiver 229 may be an encoder, and thesignal transceiver 229 may cooperate with theexternal antenna 228 for receiving and sending instruction signals from thecontroller 21, so as to realize the communication between thetrolley 13 and thecontroller 21. Reference is made toFIG. 17 , where anactuator 230 is provided at the bottom part of at least one of thetrolleys 13. Theactuator 230 can receive an instruction signal from thecontroller 21 to control the start and stop of the driving rollers of the plurality oftrolleys 13. Oneactuator 230 can be connected with the driving rollers ofmultiple trolleys 13. - Apparently, the above-mentioned
signal transceiver 229 andactuator 230 may not be provided separately, and thecontroller 21 may have modules integrating the functions of the two devices, so that thecontroller 21 can perform direct control. Those skilled in the art can easily ascertain how to realize the signal transmission between thecontroller 21, theactuator 230, and thesignal transceiver 229. For example, thecontroller 21 can be a microprocessor, and its functions can be realized according to the internal program thereof. This will not be repeated here. - In the sorting system of the present disclosure, the
trolley 13 is transported in the first horizontal direction F1, and the packages are sorted above therack 11, and returned below therack 11. This can reduce the pitch of thetrolley 13, and save the transportation resources for smaller packages. At the same time, the utilization rate of occupied space is improved. Thecontrol system 2 controls the conveying mechanism 1 of thetrolley 13 to transport the packages in the first horizontal direction F1, and can independently control the sorting and conveyingmechanism 132 of eachtrolley 13 to transport the packages in the second horizontal direction F2. This helps to realize the automated transportation of the sorting system, saves labor, and can automatically control the transportation of eachtrolley 13 in the second horizontal direction F2. Thus, the more accurate throwing and correction of the package is realized. - Exemplary embodiments of the sorting system proposed by the present disclosure are described and/or illustrated above in detail.
